The Front Cover shows the collision of balls in an oxidative transformation of primary amines to aldehydes, ketones, and nitriles in a jar. The power generated by the impact is transferred from the balls to the starting materials and enables the reaction to take place. This ball‐milling process has proved to be compatible with various functional groups and works with easily accessible starting materials. More information can be found in the Full Paper by L. De Luca et al.

前盖显示了罐中伯胺氧化转化为醛，酮和腈时球的碰撞。冲击产生的动力从球传递到起始材料，并使反应发生。事实证明，这种球磨工艺可与各种功能组兼容，并且可与易于获取的起始材料一起使用。可以在L. De Luca等人的论文全文中找到更多信息。
